"Polyptych of the Misericordia"
Yispolyptych encapsulates the stark simplicity and geometrical exactitude for which Piero della Francesca is most known. The form of the Madonna is almost perfectly symmetrical and is in itself formed of a series of geometrical shapes: her head is a perfect oval, her neck is cylindrical, and the folds of her robes are comprised of triangular forms and parallel lines. The gold background, a specific request of the confraternity, forced Piero to abandon the landscaped backgrounds, of which he was so fond. In a response to this restriction, Piero created space with the figures themselves. For example, the Madonna's curved robes echo an apse, an architecturally significant part of church designs, and Piero foreshortened the feet of the four saints on either side of her, suggesting that they are standing in a physical space instead of the featureless gold field. The use of limited colors as well as simple geometrical shapes give the polyptych an almost modern sense of "unreality" that prompts solemn contemplation on the part of the spectator.
